I sure wish it were wrong. If macOS’s text rendering primitives could be used asynchronously or concurrently the situation would be significantly better. I’ve spent probably hundreds of hours trying to make it fast but I’m convinced it’s only possible if you work at Apple (as they have done quite well with Terminal by using lots of hacks that are unavailable to me)

(As a person who just looked away from a nearly full-screened 4k iTerm2 running the metal renderer, thank you for your efforts)

Do you have any leads on the kinds of hacks they do? And does emacs have to do the same hurdles? It looks fine by me. (Mayhap I'm looking at the wrong things?)

What do you mean by “primitives” here?
